I recently purchased a brand new laptop with win7 64bit and the only thing 32 bit it didn't like is drivers. It runs 32bit apps fine. If you have old hardware that doesn't have a 64bit driver, thats where you will run into the problems. My Vista desktop is still 32bit and I wish I would of got it 64bit. 32bit is way too limiting on memory.
